AI Technical Summary

Technical Problem

Conventional anti-slip structures on cooking chopsticks, such as annular grooves, fail to efficiently entangle slippery noodles like pasta and lack an active grasping function, especially when dealing with large quantities, and the design parameters of cross-sectional shapes are not diverse enough.

Method used

The cooking chopsticks feature cross-shaped projections formed by intersecting linear projections at different angles on the tip region, with adjustable spacing and length, and optionally a third linear projection perpendicular to enhance gripping, along with varied cross-sectional shapes like circular, elliptical, and triangular, to securely entangle noodles.

Benefits of technology

The design improves cooking efficiency by securely gripping slippery noodles with minimal effort, providing a firm grip for large quantities and allowing versatile design options.

Abstract

This product provides cooking chopsticks that allow for secure and easy gripping of slippery noodles such as pasta when cooking them in a pot, and efficiently entanglement of the noodles, thereby contributing to improved cooking efficiency. [Solution] A first linear projection (31) and a second linear projection (32) are formed on the outer circumferential surface of the tip region (22) of the chopstick body (20), inclined at mutually different inclination angles in the axial direction of the chopstick body. These first and second linear projections are arranged in multiple stages in the axial direction so as to intersect each other to form a multi-stage cross-shaped projection (30). In addition, if necessary, a third linear projection (33) is provided between the cross-shaped projections (30) in a direction perpendicular to the axial direction of the chopstick body.
